I have not read the book and I will not read it until the summer at the earliest. I will be reading A New Kind of Christian for a class later this quarter.

I'm fascinated by the dialogical format he has chosen. Many great writers and thinkers have used the dialogue format to get a point across that the audience won't "get" if the author writes it in a more typical format. Plato, Erasmus, Galileo and others used the dialogue to get their point across in an unfriendly environment. It's unfamiliar enough today that people often miss how old and revered this format is. I welcome his approach. After I read his stuff I'll let you know whether I think he is Plato's peer.
